every data type. To get the scalar variable found in the glob, you have
to dereference the glob as if it were a scalar:
my $g = $main::{$Player{Location} . "::"}{Options};
my $value = $$g;

my $value = ${ $main::{$Player{Location} . "::"}{Optio
hash for @result instead of the array like I
did.

%hash', whereas $hash->{$key} means that you have a hash reference stored
in $hash. Your print() line, therefore, should be:
